Extend the time range of scope_sink_f?

Hey all,

I want to plot a slowly varying output. That is, I want to compute the
moving window rms of the signal from USRP taking a 1sec window of
signal.That means, the rms power of 500KSamples(i am using
decimation=128) at a time.

Then I want to plot 10 consequetive rms values(signal of duration
10*1sec)in a plot window as bar graph in real time. Can I do that using

I see that the time length of the signal plotted on the scope that uses
scope_sink_x is 5msec by default. How can i extend this time length to
the 10 sec, i listed above.

Or is there some other way to do this plotting?
